QT40.242 Puls AC/DC Power Supplies

Puls QT40.242 PULS QT40.242 is a power supply unit designed for AC/DC conversion with a 50% power reserve. It supports DIN rail mounting and operates within an ambient air temperature range of -25 to +70°C. This unit features an extended lifetime and includes a DC-OK relay contact output. It provides a rated current of 40A at 24Vdc and 34.3A at 28Vdc, with a derating to 24W between +60°C and +70°C. The QT40.242 utilizes screw-clamp connections and accepts a wide range supply voltage of 323Vac-576Vac across various nominal voltages (380Vac / 400Vac / 415Vac / 440Vac / 480Vac / 500Vac / 525Vac; 47-63Hz) with a 3-phase input. It belongs to the Q-series and is housed in an aluminium casing with dimensions of W110mm x H124mm x D127mm. Designed for a 3-phase network, it has a net width of 110 mm and offers a rated power of 960W (up to 1440W short-term for 4s). The output voltage is adjustable between 24Vdc and 28Vdc. Protection features include output overvoltage protection and active input inrush current limiter, with overload and short-circuit current protection supporting both series and parallel operation. The unit is resistant to back-feeding loads up to 35V. It achieves an efficiency of 0.952 to 0.953 depending on the input voltage, with a peak current consumption of 6A max. inrush. The start-up delay ranges from 500-600s, with a rise time of 35-40ms and a hold time of 25ms. Power dissipation/losses are 47.3W to 48.4W, depending on the input voltage. Electrical durability varies with conditions, reaching up to 475,000 hours at 25°C and 20A output with a 3AC 400Vac input. Ripple is maintained at 100mVpp, and the output stage capacitance is 10200 µF.
